HOT-WATER AND HOT-AIR HEATINGwFURNACE.

SPECIFICATION forming part bf Letters ratnt No. 547,237, dated october 1, 1895. Application filed .Tune 27, 1894. Serial No. 515,813. (No model.)

To all whom it may concern.-

Be it known that I, EDGAR W. ANTHONY, a citizen of the United States, residing at Brook line, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Hot-Water and Hot-Air Heating-Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a hot-air and hot- Water heater in which the Water-heating shell is arranged to extend across the fire-pot from the grate-surface upward and to thereby divide the flre'pot into two parts in either or both of which fire may be maintained and which permits, practically, the entire Wall of the radiator about the re-pot to be used as an air-heater, while the Water-heating chamber is so located that it receives heat from the portion of the fire Where it can best be given and spared, the construction differing from the ordinary construction of this type of heater, Where the Water-heatin g chamber is generally disposed around the fire-pot and the heat-radiating surface of the heater thereby decreased, While the center of the re or firepot is not utilized directly for the purpose of heating water.

The invention has other advantages, and among them I would name' this: that the fire or heating power of the furnace may be reduced by using one half ofthe fire-pot. When this is done, it will be desirable to keep the other half of the fire-pot filled or substantially filled with ashes to prevent a draft being established through it. When the furnace or heater is so used, the grate is constructed in sections, or so that one part may be manipulated Without operating the other, whereby the ashes in the part not used remain undisturbed.

Referring to the drawings, Figure l is a view in vertical sectionV upon the dotted line of Fig. 2. Fig. 2 is a View in horizontal section upon the dotted line of Fig, l. Fig. 3 is a View in vertical section at right angles to that represented in Fig. 1.

The furnace has the outer casing or shell A, the air-heating chamber B, and the radiator-shell O, Which are similar in construction,

. which extends across it, preferably from front to back and from the grate-surface upward 6o to the combustion-chamber. (See Fig. l.) This shell is hollow throughout, and in the type of furnace shown has at its back end, near or at the bottom, the extension e on each side for the purpose of affording means by which the inlet or return pipe F may make direct connection with the chamber of the shell without bending or without passing through an indirect flue. The central parte of the shell may extend upward somewhat 7o into the combustion-chamber, and if the shell is made narrow it may be somewhat enlarged,

as represented at c2, to receive the lower end ofthe outgoing pipe F. The shell D rests upon the flange or ledge cl2, and it may be suitably attached to the radiator-shell. I prefer that it extend from the back forward, in order that both divisions or sections d d of the firepot may be reached from a common feed-passage G; but this is not absolutely es- 8o sential, because there may be a separate feedpassage for each of the two sections d d', if desired. By locating the shell E so that it crosses the fire-pot when a full fire is employed-that is, one in both sections of the pot-a very large heating area is obtained and one that is Very desirable, because of the intensity of the fire upon each side, while at the same time the airheating power of the furnace is not diminished, because the radia- 9o tor about the fire-pot is in direct contact'with the fire. Consequently, practically, the full effect of the air-heating furnace of the ordinary type is obtained and without sacrificing anything to provide a Water-heating section of great power as Well. The water-heating shell also divides the fire-pot into two' parts,

so that in mild Weather or when desired the heating capacity of the furnace may be decreased by stopping oft the tire in one section 10J and using the other section only, in which, however, a lively fire may be maintained, if

needed, thereby providing an effective way of regulating the supply of heat and at the same time making a savingin the use of fuel. It will be understood, of course, that when one division of the tire-pot is not used it is kept filled with d'ead ashes,in order that the draft of the other section may not be interfered with.

The grate prefer to form in two parts, which, while they are alike, may be independently operated. This will permit the shaking of the lire upon both sides of the central shell or upon one side only, as may be needed. I-I represents one section ofthe grate or that used with the division d', and Il the part used with the division d. The type of grate which I have represented is that in which the grate-bars or fire-supporting surfaces are triangular in form and extend from shafts capable of being rotated, and in the section H the shafts h h are geared together by the gears h2 and are rotated by the prolongation of the shaft h. The section 1l has the shafts h3 h4 geared together, and they are both turned bythe prolongation of the shaft h4. (See Fig. 2.)

Any type of airheating organization may be used and in the one represented in the drawings the combustion-chamber D is represented as connected with a base-flue M by the ordinary ii-ues fm, which are connected at their upper ends with the combustion-chamber and extend downward through the airheating chamber B to the base-liuc M, which at its rear end opens into an uptake m. (See Fiff. 2.

Iwo)uld say that I consider my invention would be practiced if the shell were not eX- tended entirely across the hre-pot, but only into it to any desired extent. Of course when so employed it would not divide the tire-pot into two separate parts. I would also say that the shell E may not have the extension c and may have the returnpipe F, extending directly backward through a hole in the uptake m.

Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United Statesl. Ina hot air and hot water heater, the Water shell E herein described extending across the fire-pot and upwardly into the combustion chamber having the enlargements e, e2, as and for the purposes described.

2. The combination in a hot air and hot water heater of the grates, H, I-I, the tire-pot sections d, cl', separated by the water shell E, and the common feed passage G, as and for the purposes described.
